It is more common on soil-grown crops and can be avoided by maintaining a consistent soil moisture status. It is especially important to avoid excess water after fruit set.
Tomato cracking can also occur due to high intensity of solar radiation. Crop nutrition can help reducing the incidence of tomato cracking.
Boron has a positive influence on the level of tomato cracking and shelf life of the tomato fruit. Any cracks on the fruit shoulder increases water loss and susceptibility to pathogen attack. Potassium and calcium deficiencies also increase the risk of cracking in tomatoes.
